"We are seeing it more and more, so yes, the problem is growing," said Sgt. Jamin Martinez, of the Sacramento County Sheriff's Department, who works with gang and narcotics investigations. "You're taking large amounts of butane and you are compressing a butane gas into a canister to create an oil. All that gas has to go somewhere. If it doesn't escape and it gets ignited, it's going to blow up."

Explosive materials are used to extract THC from marijuana to create a highly potent form of the drug.

Martinez said aside from taking note of the drug traffic, people might not be aware if someone was making honey oil next door.

“Butane is commonly used to manufacture honey oil," Martinez said. "Butane doesn't really have a great odor (where) you can say, ‘That's definitely butane gas.'"

People who live in the Rancho Terrace apartments said that makes sense.
